I'm just curious how many people used those programs like King or Sporty's for their ground training and how many people just worked with a CFI? Did some people do both?
I'd hazard to guess that most CFIs will expect you to do a lot of homework to learn your groundschool material. It's a lot cheaper for you to do it that way, too. The more you learn on the ground, the less time you'll be paying your instructor his hourly rate to spoonfeed you.
Doing lots of home study is absolutely the best way to minimize your training costs.
My CFI assigns chapters for me to study on my own, and I just use him to clarify points I don't understand (usually when taxiing or waiting for clearance as we're "on the clock" then anyway). Then he questions me occasionally on things I am expected to know, usually at inopportune times like when I'm calculating a route deviation in-flight, or turning base to final.
Sounds like he's basically leaving it up to you. That's not uncommon among instructors. Just make sure that you study the books thoroughly and note that you aren't studying simply to pass the written test.
I just studied from books and worked with my CFI. The closest things to videos in those days were called "filmstrips".
